Soyuz 26

 1977-113A


Yuriy Romanenko and Georgiy Grechko stepped in to replace the Soyuz-25 crew as Salyut-6's first residents. Their spacecraft, 7K-T No. 43 (11F615A8 No. 43) was launched on 1977 Dec 10 and became Soyuz-26. It docked with the rear port of DOS 5 on 1977 Dec 11.

On 1978 Jan 16, the EP-1 crew launched on Soyuz-27, Vladimir Dzhanibekov and Oleg Makarov, entered the spacecraft. They undocked later that day and landed in Kazakhstan.

Rocsat 1

 1999-002A


The Republic of China (Taiwan) NSPO National Space Program Office contracted TRW to built the ROCSAT (Republic of China Satellite) experimental satellite. Taiwan Aerospace/Taichung and ITRI/Hsinchu, as well as the NSPO/Hsinchu integration facility were involved in building the satellite. Rocsat has a mass of 403 kg and will be launched into a 600 x 600 x 35 orbit. The OCI will determine plankton levels for fisheries management. Size is 1.1 x 1.1 x 2.0 m with two 1.1 x 2.5 m solar arrays. The Rocsat bus will also be used for some EOS missions.

In some contexts ROCSAT is referred to in Chinese by the word whose Wade-Giles transliteration is Chunghua (meaning China). Taiwan at this time used Wade-Giles rather than Pinyin. However more generally the name Formosat-1 (

\uni{ 福爾摩沙衛星一號}{ }
Fuermosha weixing yi hao) is used.

The Athena has a Castor 120 stage 1 and an Orbus 21D ESBM (Equipment Section Boost Motor).

On 2004 Jun 16 the satellite lost Sun sensor capabilities and the spacecraft was unable to keep its solar panels oriented, losing power.

ESBM was 10810 kg full 1030 em, thrust 189.2 kN, 296s Isp. 2903 m/s. mdot 65.2 kg/s.

m1/m2 = 11213 / 1433 so dV = 5972 m/s
